 Before it's non-embarrassingly releasable:
 
- - work out what to do about atimes on directories in the absence of
-   the Linux syscall magic
-    * one option is to read them during the scan and reinstate them
-      after each recursion pop. Race-condition prone.
-    * marking them in a distinctive colour in the reports is another
-      option.
-    * a third option is simply to ignore space taken up by
-      directories in the first place; inaccurate but terribly simple.
-    * incidentally, sometimes open(...,O_NOATIME) will fail, and
-      then we have to fall back to ordinary open. Be prepared to do
-      this, which probably means getting rid of the icky macro
-      hackery in du.c and turning it into a more sensible run-time
-      abstraction layer.

  - cross-Unix portability:
     + use autoconf
        * configure use of stat64

       straight to terminfo: generate lines of attribute-interleaved

-    + I think the attribute-interleaved text might be possible to do
-      cunningly, as well: we autodetect a basically VT-style
-      terminal, and add 256-colour sequences on the end. So, for
-      instance, we might set ANSI-yellow foreground, set ANSI-red
-      background, _then_ set both foreground and background to the
-      appropriate xterm 256-colour, and then display some
-      appropriate character which would have given the right blend

-       * current best plan is to simulate the xterm-256 shading from
